A typical application using L6229 is shown in Figure 24. Typical component values for the application are shown
in Table 9. A high quality ceramic capacitor (C
power pins VS
and reduce high frequency transients generated by the switching. The capacitor (C
input to ground sets the shut down time when an over current is detected (see Overcurrent Protection). The two
current sensing inputs (SENSE
length as short as possible in the layout. The sense resistor should be non-inductive resistor to minimize the di/
dt transients across the resistor. To increase noise immunity, unused logic pins are best connected to 5V (High
Logic Level) or GND (Low Logic Level) (see pin description). It is recommended to keep Power Ground and
Signal Ground separated on PCB.
